MILTON O. SCHUR FIG-4 IVE! nited States CIGARETTE Milton 0. Schur,Asheville, N.C., assignor to Olin Mathieson Chemical Corporation, acorporation of Virginia Filed Nov. 17, 1958, Ser. No. 774,361

1 Claim. (Cl. 131-9) The present invention relates to cigarettes and inparticular to a tipped cigarette.

The language tipped cigarette is utilized to denote that class ofcigarettes, conventional or filter type, wherein a band of paper isdisposed about the end of the cigarette which is introduced'into themouth of the smoker.

For example, tipping may take the form of a paper band simulating a bandof cork or the like. i

A particular feature of the invention is the provision of a cigarettehaving a novel structure.

A further feature of the invention is the provision of a tippedcigarette where the tipping material is formed with a porous structureor with microscopic openings.

A further feature of the invention is the provision of a tippedcigarette where the tipping material is formed with a plurality ofopenings of such small size that they are not obvious and are scarcelyperceptible to normal vision.

A further feature of the invention is the provision of a cigaretteincluding a column of tobacco, a wrapper, and a band of tipping paperjacketing the wrapper where the wrapper is formed with at least oneobvious opening While the tipping paper is porous or otherwise formedwith a plurality of obscure openings; the tipping paper jacketing thewrapper so that the porous structure of the tipping paper registers withand overlays the wrapper opening.

A cigarette forming an exemplary embodiment of the invention andembracing the principles thereof may comprise a column of tobacco, aWrapper encircling the tobacco, said wrapper being formed with at leastone opening and tipping paper disposed about the cigarette so as toenclose and overlay at least a portion of the wrapper, at least aportion of the tipping paper being of a porous structure, the tippingpaper being so disposed with respect to the wrapper that some of theporous structure registers with the wrapper opening.

Other features and advantages will become more apparent from thesucceeding specification when read in conjunction with the appendeddrawings in which:

Fig. 1 shows a cigarette with which the principles of the presentinvention may be utilized;

Fig. 2 is a showing of a portion of the cigarette of Fig. 1 somewhatenlarged and with portions broken away for clarity;

Fig. 3 shows an alternative embodiment of the invention wherein thewrapper extends the full length of the cigarette;

Fig. 4 illustrates an example of porous tipping paper; and,

Fig. 5 shows obvious openings in the wrapper band.

Referring now to the drawings, specifically Figs. 1 and 2, there isshown a cigarette indicated generally by the reference numeralcomprising a column of tobacco 11 atent O ice enclosed by a wrapper 12and including an abutting filter plug 13.

The filter plug and the wrapper column of tobacco are joined in abuttingrelationship by a band 14 of tipping paper in well known fashion.

The wrapper 12 is formed with a plurality of openings 16 while thetipping paper includes an area or ribbon of obscure openings (shownsomewhat enlarged for clarity) indicated by the reference numeral 17.

As in apparent in Fig. 2, the tipping paper is so disposed with respectto the wrapper 12, that some of the openings in the tipping paper fallinto register with the wrapper. In this fashion, there is provided aconduit from the atmosphere to the interior of the cigarette so that thesmoker upon taking a drag induces air to enter the conduits.

A convenient way of characterizing the openings in the tipping and inthe wrapper and a convenient aid in defining the relative size of thetipping openings as against the wrapper openings is to refer to theformer as being microscopic in size while the latter openings aremacroscopic.

Furthermore, it is intended that the tipping band be securely fixed tothe cigarette body as by gluing.

Fig. 3 shows an alternative embodiment of the invention wherein aWrapper having macroscopic openings 160 is shown enclosing a column oftobacco 110 and a filter plug so that the wrapper extends the fulllength of the body of the cigarette. v

The tipping paper shown jacketing the wrapper is formed with a band ofmicroscopic openings which fall in register with the openings160.

Obviously the plug 130 may be replaced with tobacco so that a stillfurther embodiment of the invention may be constructed so as to embracenothing but tobacco within the wrapper portion thereof.

Figs. 4 and 5 show typical tipping material in the form of paper band 18having a ribbon of microscopic openings 19 and a typical wrapper paper21 having macroscopic openings 22 respectively.

Obviously the width and finish of the tipping paper, indeed, thematerial from which the tipping is fabricated, is not critical.

Correspondingly, the size, number and conformation of the holes 22 isnot critical so long as the cigarette embracing these elements isconstructed in accordance with the preceding description of theinvention.

' It is intended that a cigarette constructed in accordance with theprinciples of this invention will be effective when smoked to bringabout the introduction of air into the body of the cigarette through thelateral or side openings formed in the tipping and in the wrapper inaddition to the normal draught of air that is drawn longitudinallythrough the burning cone and the column of tobacco of the cigarette.

Obviously a wide variety of opening structures can be devised, i.c., thearea of the openings in the wrapper may be increased or decreased toincrease or decrease the volume of air drawn thereto, without departingfrom the spirit and scope of the invention.

What is claimed is:

A cigarette comprising a colunm of tobacco, an abut ting filter plug, awrapper encircling the column of tobacco, a band of tipping materialencircling the wrapper and the plug, said wrapper being formed with atleast one macroscopic air opening in a margin thereof adjacent saidplug, said tipping material being fixed to the wrapper and being formedwith a plurality of microscopic air open.-

ings, said microscopic openings being circumferentially disposed aboutsaid tipping material, the tipping material overlaying the wrapper andbeing so positioned with respect to the wrapper that a least some of themicroscopic openings fall in register with the wrapper opening toprovide communication from the atmosphere to the interior of thecigarette through the tipping material and through the wrapper, saidtipping openings being scarcely perceptible to normal vision.
